2 Agenda Status update of the project Overview of Reactor Vessel Internals Segmentation Environmental update 2

3 2012 Safety Statistics 2012 Statistics 6 OSHA Recordable Injuries (all categorized as Strain/Sprain/Pain) - Focus is being placed on Human Performance tools and training. Injury Body Location 9 Back/Shoulder 3 OSHA 7 Knee/Leg 2 OSHA 10 Hand/Finger 1 OSHA

4 Safety Focus 2012 on Sprains/Strains/Pains Outside of RCA for mgmt attention Added senior mgmt team observation program modeled after Ford Motor Co. This is in addition to formal daily mgmt observations. Stretching, limbering, getting mechanical advantage for work Proper equipment, proper use of equipment Human Performance tools; attention span, work planning involvement of craft (weekly safety meetings focus) Murphy s up ysalley Training 4

14 Major Fuel Tasks Schedule Fuel Modifications and Inspections Complete for all 2, fuel assemblies Dry Cask Storage Canisters First canisters set to arrive summer 2012 ISFSI Engineering complete Construction begins summer 2012 Fuel Crane Upgrade New trolley assembly complete Installation begins summer 2012 Visual Inspection Fuel Transfer Operations Scheduled to begin spring 2013 Damaged Fuel

15 2012 Major Work Remaining ISFSI construction Heavy haul path construction U-1 reactor vessel prep work U-1 SGs removal Complete U-2 reactor internals segmentation Complete Asbestos remediation in the Aux building VCC construction ti Fuel building crane upgrade Continue MARSAME characterization of the turbine building 15

16 Reactor Segmentation The major components of the reactors are: The reactor vessel (RV); and The reactor internals (RVI) RV and RVI now require remote cutting because of the levels of radioactivity All segmentation performed in reactor cavity Internals under water Vessel dry (after cavity draining) All cuts performed mechanically (currently)

38 Stewardship Biodiversity Protection Illinois Beach State Park located on the North and South side of the property. p Examples of Wildlife Protection Canada Goose and Goslings Blanding s Turtle Inspections and Notifications Snakes Fox Snake Garter Snakes 38

39 Canada Goose and Gosling Rescue A pair of Canada Geese nested on a roof top IDNR inspected the nest site and advised Six Goslings were rescued from the roof top and relocated to the lake front After several minutes the mother goose flew from the roof top to the lake front. The gander stood a 39 protective watch from a distance.

40 Snake Rescue and Release Snakes rescued from railroad tracks scheduled to be repaired as part of the decommissioning work. Environmental coordinated efforts with: IDNR Lake Forest Wildlife Discover Center College of Lake County Biology Professor High School Teacher/Local Resident During the Spring, the rescued snakes were returned to an artificial den. The den is located at the Illinois Beach State Park, north of the original snake den location. 40
